9 Claims. (ci. 2o- 523) This invention relates to. a window mounting andmore particularly to improved means for readily inserting and removing awindow or sash with respect to its frame.

The conventional double-hung windows in use today require an assortmentof auxiliary equipment such as pulleys, cords, sash weights,balancing'springs, and the like. Additionally, sueh wiilldOWconstructions are subeet te many disadvantages For example., the windowsvery easily rattle as from gusts of wind or conversely become so stuckthat it is diicult to open or close them. Further, weather strippingmust often be used to keep, out rain, drafts of air, and the like. Inparticular, washing the outside of such windows is not only inconvenientbut also hazardous, espeeiallv in the case of high build- 1,955.5'

The present invention eliminates all of these objections. A window orsash mounted in accordance with this invention requires no weatherstripping and very few auxiliary Partr- Fdrther, the windew may bequickly and easily removed as for cleaningI and then replaced, and inspite /of such ease of mounting, the window is rattleproof andthi'ckproof.

in one form the present invention includes a compressible strip formounting a window sash in its frame. The strip is folded longitudinallyto impart the compressibility and has spaced-apart pockets or openings.The strip is inserted at the folded edge between the sash and its frameto, make resilient contact therewith. Pins carried by the frame make asnap engagement with the pockets when the insertion of the strip reachesa predetermined point to hold the parts in assembly. To remove the stripand therefore also the sash, the folds of the strip are brought togetherto clear the pin and then withdrawn. In the preferred form, the mountingstrip has an enlarged edge which forms a separating rib to. space apartupper and.

lower sashes.

The yaccompanying drawing illustrates a presently prel ferred embodimentwherein:

1rigurel 1 is. a front elevation of a,,double-hungA window embodying theinstant window mountingev y Figures and 3 are sections of Figure 1 onthe lines ll-ll and III-HI, respectively;

Figures 4 and 5 are perspective views of a side and top strip,respectively, used in the window mounting; and

Figure 6 .is a fragmentary. sectional view similar to Figure 2 of aconventional double-hung window.

`Referring to the drawing, a double-hung window generally shown at 10includes an upper and lower window or sash 11 and 12, respectively, inwhich glass panes 13 are conventionally carried. A frame 14 has sidejambs for mounting sashes. The frame encloses the sashes and has a strip15 fixed at the top and strips 16 and 17 fixed at the sides. The uppersash 11 is resiliently held against the strips 15, 16 and 17 bylongitudinal mounting strips or fittings 18 and 19 which extend down thesides of the frame 14. Each mounting strip is preferably metallic andincludes a somewhat rectangular edge or guide portion; one (outer) sideof the fitting member is "t 2,777,175 ce Patented Jan. 15, 1957 extendedand folded back on itself to form a resilient wedge or spring plateportion 21. Pins 22 carried by the frame 14 engage indented pockets oropenings 23 which are spaced longitudinally along the mounting strip tohold the parts in assembly. A separating strip 24 is shown secured tothe top of the frame 14. and spaced from the strip 15 to receive theupper sash 11 therebetween.

Transversely-extending outer side panel portions 26 are positioned forsubstantially flush mounting against the jamb portions of the frame 14.One end of each base or side panel portion is, as shown in Figure 2,connected by a spring-like or resilient connection to thetransverselyextending inner spring plate portion 21 to thus provide yarail for the operative movement of the sash 11 or 12.

The spring portion 21 extends transversely from its connection to 216.in an inwardly-diverging relationship that defines a substantiallyV-shaped section therewith.

The guide portion 20. projects inwardly from the panel portion 26 at anagle thereto and, with the diverging end of' the spring plate 19.,defines a somewhat box-like section for guiding the side of the sash initsV operative movement. More specifically, ythis box-like section, asshown in Figure .2, is in guiding engagement with the adjacent cornerportions'of the sash. Sincethe sides of the sash 11 and 12 are sloped orinclined inwardly in a somewhat complementary manner with respect to theplates 2 1 which tightly abut thereagainst, it is apparent that aresilientwedging type of action is employed to hold each sash in itsoperative position within the frame 14,

It is a simple matter to remove either or both of the sashes 11 and 12by outwardly forcing or compressing the plate portions 19 against theresiliency of their mountings. That is, the spring plate portion 19, asbiased to resiliently abut the sash, Vnot only holds the sash in anoperative position without rattling and weather-strips the installation,etc., but also makesvpossible a simple procedure for installing andremoving the installation from between jam portions of a conventionalIframe 14. s

The lowerl sash 1,2, bears against the rectangular edges, of themounting stripsr 18. and 19 and is itself held in position by mountingstrips 13a and 19,11 which extend up the sides of the frame 14 and aresimilar in construction to the mounting strips 18 and 1,9. Pins 22a holdthe Strips 18d and: 1.941 in position. in. a manner like. that 0f. pinsZ2, If desired,- a second separating strip 215 may be secured to the topof the frame `1,4 and'spaced from the.

operation. Also, the pins may be carried by the sashes, and the openings23 may be in the frame. Due to the compression of the resilient folds ofthe mounting strip as a result of the insertion, the pin is quicklyforced into the pocket and the side 26 of the strip is quickly flattenedagainst the frame 14. Here and in the claims such a fitting is referredto as a snap engagement or snap holding engagement and is meant toindicate a quick engagement of the designated parts and subsequent quickdisengagement as hereinafter mentioned. The second molding strip for theupper sash 11 is next similarly installed. The lower sash 12 is now heldagainst the rectangular edges 20 while strips 18a and 19a are insertedin a like manner between the lower sash and the frame until the pins 22asnap into the pockets or openings 23 of those strips. The compression ofthe folds of each strip is not sulciently great to prevent raising andlowering of the sashes.

To disassemble the present Window construction, the folds of one of themounting strips cooperating with the lower sash are brought together toclear a pin 23a and then withdrawn from the assembly. This is readily accomplished by pushing against the rectangular edge 2.0@ of the strips18a or 19a substantially in the direction indicated by the arrow 27.Thereaftenthe order given in describing the assembly of the windowconstruction is followed in reverse. However, it is also possible toremove the sashes after only one of the mounting strips is withdrawn,and ordinarily this procedure is followed when the sashes are to beimmediately replaced as after cleaning them.

It is emphasized that the rectangular edges on the mounting strips bearagainst the sides of :the sashes and prevent them from moving forwardlyout of the frame. Also, the rectangular edges Z serve as a separatingrib and space apart the sashes 11 and l2. Further, the rectangular edges20a and the separating strip 2S form attractive trim work around theinside of the window. This construction thereby eliminates standardstrips like strips 2S and 29 secured to a frame 30, as shown in theconventional double-hung window of Figure 6, which the sashcs 3l and 32loosely contact in order to allow raising and lowering of those sashes.The present window mounting, in contrast, eliminates any opportunity forrattling and the need for weatherproofng by means of the resilientstrips. indeed, the strips themselves afford a weatherprooiing action.Additionally, also because of the resilient nature of the mountingstrips 18 and 19 against which the sides of the sashes slide, the sashesdo not stick. Further, the sashes are easily removed for safely washingthe panes 13 within the room in which they are used and then quicklyreplaced as described.

if desired, ythe strips 15a and 19a may be solid, that is, free of theopenings 23. ln this case, in Order to retain such a strip, the pin 22amay be driven into the frame to make a snap engagement against the sideof the rectangular edge a which faces the room after the strip 18a orE9n has been inserted -that far,

While the foregoing disclosure describes a `presently preferredembodiment, it is understood that the invention may be practiced inother forms within the scope of the following claims.

We claim:
